SIRIUS Safety Integrated: Protective door monitoring by means of non-contact safety switch to SIL 3 or PL e with a safety relay

  • Entry
  • Associated product(s)
This entry contains information about protective door monitoring by means of non-contact safety switch to SIL 3 or PL e with a safety relay

 

Task

Protective doors are frequently used to fence off danger zones. These are monitored for position and, if necessary, the area from which the hazard emanates is switched off.

Solution

The position of a protective door is monitored via the non-contact safety switch. When the monitored door is opened, the safety relay triggers and opens the enabling circuits, switching off the power contactors in a safety-related manner. If the door is closed and the feedback circuit is closed, the Start button can be used to switch on again. 

The 3SE6315 non-contact safety switch has two channels internally and possesses its own diagnostics capability. Because of this, and because it is tamper-proof thanks to its RFID technology, a redundant safety switch is not required to achieve up to PL e per ISO 13849-1 or SIL 3 per IEC 62061.
